- Basically maintain a hidden DIR* inside fhandlers.
- lseek has to be tweaked to allow basic seeking on the directory
descriptor.
- the current implementation does not keep the dir positions
between duplicated descriptor in sync. In fact, every descriptor
keeps its own copy of the DIR* and after dup/fork/exec, the
directory position is reset to 0, i. e., to the start of the
directory, as if rewinddir() has been called on the new descriptors.
While this behaviour isn't yet covered by the Issue 8 draft,
a bug report along these lines exists and will probably be
picked up for TC1.

Use the same name as glibc & gnulib to indicate "newlib itself is
being compiled". This also harmonizes the codebase a bit in that
_LIBC was already used in places instead of _COMPILING_NEWLIB.
Building for bfin-elf, mips-elf, and x86_64-pc-cygwin produces
the same object code.
Move common content of the various <sys/dirent.h> and the latest FreeBSD
<dirent.h> to <dirent.h>.

MAXNAMLEN is a BSDism.
Use the proper internal macros instead of !_POSIX_SOURCE. telldir and
seekdir are XSI, scandir and alphasort are POSIX.1-2008, and scandirat
is GNU.

* libc/include/sys/unistd.h: Removed definition of MAXNAMLEN.
* libc/include/dirent.h: Added definition of MAXNAMLEN if
not defined by sys/dirent.h.
* libc/posix/execvp.c: Added include of dirent.h to get
MAXNAMLEN value which used to be in unistd.h.
